I,"RoBERfr Nl'SrEwARr,of the ycity of Philadelphia, in `the `State ofPennsylvania have invented a `certain Improvement in Gas-Burners, ofwhich-the following isa specification.` v l Nature "and Object ofltheInvention'. l, i `My inventionrelate's'to the construction and mode e ofapplying and securing the 4arched fr warming-plate of a bat-winggas-burner, the object being to 4simplify `and lessen the cost fofconstrnction'and application l without reducing or 'impaiiing its-eiiic-iency 4as a` i warmer for increasing the strength of the light,without increasing the zfloiv of thegas through the burner.

Description of `the Accompanying.Drawings. i Figure 1 is an elevationofa bat-wing gas-burner, i `showing the face side of my inventionapplied thereto; Figure 2; is `a like elevation of the saine burner, lshowing an edge or. side View of the invention applied; l p `Figure 3'isaffront' view-,showing the face side of the warmer detached from theburner; and p `.Figure 4 isa like view, showing the rear side of the`said detached warmer. p p i p General Description. A p p l A is acommon gasburner,itbe outlet of which consists` of a straight,narrowslit, sawed vertically down- `ward across the middle of its upper,and so as te come f into communication with the bi'eif-thefburner,whereby a broad fiat flame, called abat-wing flame, is proi l ducedby'the` ignited gas as it is dischagedthroug'h the slit. l l Y r. f B isthe warming-device. It` consists of a bonnet, or cap, made'cf thinsheetn|etal,`the arched front of' which constitutes the `face side of`the `warming-plate b', `which ts overthat part of the'bnrner which. hasthe slit in t.` This plate ,is `united closely at-its, rear Vside to acap, b', which fits over that 'part ofthe upper `end ofthe burner whichis inrearof the plate b', when the whole warmer Bis properlyzappliedupon-thev .L burner -"(See ig.2.) i y lhe two endsI 3 3 of ythe4 plate-extend downward ROBERT N. sr-EwARror PHILADELPHIA,PENNSYLVANIA.

l Letters Patent No. 94,922, dated September 14,1869.v

^ 'y IMPROVMENT 1N ATTAGHMNT rfoRvG'As-BURNERS.

` i like Schedule :referred toin these Letters Patent arid making partof the same side is in the vertical planeA of the rear side of the slit,which, in the burner A, produces the bat-wing dame,

the two4 ends, 3 3, ofthe plate b extending down vertically through theappropriate slits, which are cnt 1 across in the beads 4 4,-and thelower edge'ofthe cap b at the same time resting on the upper bead 4.(See figs; l and'2.) l

The ends 3 3 are eachnotched at a point which corresponds ,with the linecfvdivjson between the two, beads .4 4, whereby the warmer BA can bereadily secured in place on the burner by means ot a fine wire tiedaround between the said beads; or, if preferred, the extreme ends of 33.of the plate b may be readily bent to a light angle against the underside of the lower bead 4.

Itwill plainly be seen that this mode of construet ing, applying, andsupporting the warmer of a ,gasburner is muchmore simple and inexpensivethan any other heretofore used, while it -is' equally effective as aheater for increasing Vthe strength of the light of a bat-wing burner,by rarifying the gas and increasing fthe current of air for itscombustion.

tially as and for the purpose hereinbefore set forth.
